Office 2007 SP2: PNG, Textboxes and Postscript Printing

We use a fair number of older Word documents that contain PNG images and text
boxes i.e. hierarchical charts. The document appears fine in print preview,
but when it is printed to a Postscript printer, text in the text boxes is cut
off almost like the image or its margins overlap.

For example, if there is a PNG image on the left and a text box on the right
and they do NOT visually overlap in any way, then the 50%+ of the text in the
text box will be cut off from the left.

The kicker?? The same documents print fine when printed to the same printer
from even the same computer WHEN OFFICE 2007 SP2 IS UNINSTALLED.

Any ideas? Given the number of documents, replacing the images is not
feasible. It is unlikely the users will re-create the charts with SmartArt
either. There is a good chance that the users will eventually have to have
SP2 or later if not a newer version of Office, so I hope to find a solution
to the problem.

Many thanks and if there are any questions, feel free to ask! Thanks.
